About Víctor

Lead mobile engineer con 13 años de experiencia liderando equipos y arquitecturas Android/multiplataforma. Ayudo a empresas a migrar a Kotlin Multiplatform, construir apps desde cero o profesionalizar la arquitectura y prácticas de sus equipos móviles existentes.


Con más de 13 años como ingeniero de software especializado en aplicaciones móviles, ayudo a empresas y equipos a:

  • Definir y liderar arquitecturas móviles, ya sea nativas (Android/Kotlin) o multiplataforma (Kotlin Multiplatform + Compose Multiplatform).
  • Migrar proyectos existentes hacia stacks modernos (Compose, KMP, MVVM/MVI) sin frenar la velocidad de entrega.
  • Construir apps desde cero con buenas prácticas desde el primer commit: testing, CI/CD, arquitectura escalable.
  • Formar y mentorizar equipos en Kotlin, Android moderno y prácticas de desarrollo.
  • Integrar IA en el proceso de desarrollo y en el propio producto (he liderado el desarrollo de un agente de IA como feature de producto).

Algunos proyectos en los que he trabajado incluyen apps de pago (Waylet, usada en todas las gasolineras Repsol), apps de logística de última milla (Citibox), y marketplaces de comercio (Klikin), entre otros, para empresas como Iberia, Eventbrite, Repsol y Citibox.

Disponible para consultoría técnica, liderazgo de equipos de forma temporal (interim CTO/lead), auditorías de arquitectura, o desarrollo directo en proyectos Kotlin/Android/KMP.
